intersectAxesBundle()

bool intersectAxesBundle ( const point & V0, const point & V10, const point & V20, const label i0, const pointField & origin, const scalar maxLength, point & pInter )

static

Intersect triangle with parallel edges aligned with axis i0.

Returns true (and intersection in pInter) if any of them intersects triangle. Used in intersectBb.

Here is the call graph for this function:

intersectBb() [1/2]

bool intersectBb ( const triPointRef & tri, const treeBoundBox & cubeBb )

static

Intersect triangle with bounding box.

Returns

true if any bounding box faces intersect the triangle, returns false if the triangle is inside the bounding box
